A 52-year-old man was found dead in the driver's seat of his tank lorry. The tank lorry was used to transport industrial wastewater to a disposal plant; the material was transferred into a storage tank with the help of compressed air. The wastewater contained methylene chloride and 2-chloropyridine. No respiratory protective equipment was used while working under these conditions. The autopsy report showed extensive edema and congestion of the brain, lung, and intraperitoneal organs. The concentrations of methylene chloride in lung and brain were reported at 398 and 67 mg/kg, respectively.

PURPOSE: The purpose of this study was to analyze factors affecting burnout among clinical nurses according to Positive Psychological Capital. METHODS: The study design was a descriptive survey and questionnaires were collected from 412 clinical nurses who worked in a general hospital in "J" city. Data were analyzed using frequency, percentage, mean, standard deviation, independent t-test, One-way ANOVA, Scheffe test, Pearson Correlation, and hierarchical multiple regression. RESULTS: In Model individual characteristics accounted for 27.8% of the influence on burnout. In model II with the addition of the 4 factors; Self-efficacy, Hope, Resilience, Optimism, individual characteristics accounted for 48.5% of the influence on burnout. Optimism and Resilience of the Positive Psychological Capital sub-variables were statistically useful as factors influencing burnout. CONCLUSION: The results indicate that it is necessary to develop active human resource management and educational programs to decrease burnout and strengthen the Positive Psychological Capital of the nurses.

Purpose: This study was attempted to identify the importance and performance of person-centered care in nurses in intensive care units (ICU) at general hospitals and to derive the priority of practical person-centered care needs and intervention by analysing their needs. Methods: A total of 156 ICU nurses who wrote a written consent participated in a survey questionnaire on person-centered critical care nursing (PCCN). The collected data were analyzed using paired t-test, Borich’s needs assessment, and the Locus for Focus Model. Results: All 15 items of person-centered care in ICU nurses were found to be significantly higher in perception of importance than performance level (t=17.98, p<.001). According to the analysis of Borich's needs and the Locus of Focus Model, person-centered care items with highest priority in ICU were therapeutic contact, comfort words and actions, and efforts to empathize with patients in the compassion category. Conclusion As a strategy to improve the person-centered nursing performance of ICU nurses in the ‘individuality’, it is necessary for ICU nurses to recognize the ICU patients as an individualized person, not as a disease or machine-dependent entity. Also, it is necessary to develop programs to improve the ICU nurses' compassion competence because ‘compassion’ was a top priority according to Borich's needs assessment model and the Locus for Focus Model.

OBJECTIVE: We examined the relationship between chronotype and sleep disturbance, and assessed various factors that might be associated with sleep disturbance in Korean firefighters. METHODS: Self-administered questionnaires assessing chronotype, depression, alcohol use, posttraumatic stress disorder (PTSD), stress response and sleep quality were examined in 515 firefighters. RESULTS: Evening type firefighters more reported depression, alcohol use, PTSD, stress response and sleep disturbance. Also evening chronotype was the most significant risk factor for poor sleep quality (odds ratio [OR], 4.812; 95% confidence interval [CI], 2.448-9.459), even after controlling for all other variables (OR, 3.996; 95% CI, 1.806-8.841). CONCLUSION: Chronotype was the factor most strongly associated with sleep disturbance, and therefore should be considered an important variable in sleep quality, particularly in occupations involving stressful activities, such as firefighting.

BACKGROUND: N-nitrosomorpholine (NNM) is a genotoxic hepatocarcinogenic agent. Preneoplastic and neoplastic hepatocyte lesions were induced in rats by oral exposure to NNM (200 mg/L) in a stop model experiment. Platelet-derived growth factor receptor (PDGF-R) is a tyrosine kinase receptor that works with PDGF, stimulating cellular growth and proliferation. The present study was designed to determine the role of PDGF-R alpha expression in hepatocellular neoplasms and precursors. METHODS: Seventeen rats out of a starting number of 30 died. From the fifth week until the 24th week one or two rats were evaluated. Preneoplastic single cells or foci, foci of altered hepatocytes (FAH) hepatocellular adenomas (HCA) and hepatocellular carcinomas (HCC) were studied histologically, and the expressions of GSTp and PDGF-R alpha by immunohistochemistry. RESULTS: At the fifth week, GSTp +single cells showed PDGF-R alpha expression (20.8+/-5.8%). At the sixth week, GSTp +single cells, located at periportal areas, co-expressed PDGF-R alpha (43.4+/-9.6%). Over the next several weeks periportal hepatocytes showed weaker PDGF-R alpha expression but no GSTp. GSTp+FAH, and all HCA, demonstrated no PDGF-R alpha expression. However, nine out of 10 (90%) HCC showed PDGF-R alpha expression. CONCLUSIONS: These data showed that there were two peaks of PDGF-R alpha expression, and suggest that the earlier expression is related with the response to NNM-induced hepatocyte toxicity, and that the later response is associated to malignant transformation.

BACKGROUND: Oral allergy syndrome(OAS) is composed of it,ching sense and edema in oral cavity, lips, throat, pharynx, and larynx following eating some fresh fruits or vegetables. It has been known that most of patients with OAS are allergic to pollens. Common epitopes were found among pollens, fruits and vegetables. Although OAS is a common farm of food allergy in adults, this is the first epidemiologic study of OAS in Korea. MATERIAL AND METHOD: One hundred and fifty one patients who showed positive skin reaction to pollens were telephone-interviewed. Investigation of the prevalence and clinical manifestations of OAS was possible in 81 patients. RESULT: The prevalence of OAS among these patients was 34.6% (28/81). OAS was found in 24(48%) out of 50 patients sensitized to tree pollens, whereas 4(13%) of 31 grass or weed pollen-sensitized paients had OAS. Most common causative food was apple and all of 17 apple- OAS patients were sensitized to tree pollens. Peach was the second common food and 14 of 15 peach-OAS patients were sensitized to tree pollens. Besides oral symptoms, rhinitis, asthma, diarrhea, nausea, vomiting or generalized urticaria were accompanied in half of the OAS patients (14/28). Some patients showed OAS to some unique Korean foods such as dropwort, taro and Aster. CONCLUSION: OAS was very common in pollen-sensitized patients. Larger epidemiologic studies are needed to find unique Korean foods and their antigensm causing OAS.

PURPOSE: This study was to compare quality of life, sexual function, and depression between a group with sexually active women and the other with sexually inactive women who undertaken mastectomy. METHODS: Participants were 106 breast cancer patients who had spouse and participated in self-help group in Gwangju, Korea. The questionnaires were consisted of Quality of Life Index-Cancer Version (Q.L.I.-C), self-rating depression scale, and Female Sexual Function Index (FSFI). Data were analyzed using the SPSS Win 14.0 K+ for descriptive statistics, t-test, ANCOVA, and MANOVA. RESULTS: There were no homogeneity at age, job, educational years between sexually active vs. inactive groups. In sexually active group, mean age was 46.1, having job 34.5%, bachelor's degree 38.2%, and pre-menopause 79.2%; for the inactive group 49.6, 10.4%, 12.5%, and 52.7% seperately. There were significant differences in quality of life, sexual function, and depression between two groups when four covariates were controlled. The quality of life and sexual function in sexually active group were significantly higher than inactive group(p<0.001). The depression in sexually active group was significantly lower than inactive group(p<0.001). CONCLUSION: This study indicates that nurses are needed to counsel and intervene psychosexual approach especially sexually inactive women with breast cancer during the recovery period.

To investigate the imbalance of the cytokine production profile of T cells from atopic asthmatics, we measured concentrations of IL-4, IL-5 and IFN-y by ELISA method in the culture supernatants of peripheral blood mononuclear cells(PBMCs) and Derrnato-phagoides pteronyssinus(Der p) J-stimulated PBMCs from Der p-sensitized atopic asthmatics, Der p-sensitized healthy atopits, non-atopic asthmatics and healthy non-atopics. The suppressive effect of IFN-y on cytokine production of Der p J-stimulated PBMCs was also examined. The PBMCs from atopics showed higher IL-4 and IL-5 production in response to PHA +TPA and higher IFN-gamma production in response to Der p Jq compared with non-atopits. The Der p J-stimulated PBMCs from atopics showed a tendency of increased IL-5 production in response to Der p J and higher IL-4 and IL-5 production in response to PHA+TPA compared with non-atopics. IL-5 production of Der p J-stimulated PBMCs from atopics was suppressed by IFN It is suggested that an imbalance in IL-4, IL-5 and IFN-y production is a feature of the atopic state. The TH2 characteristics of allergen-stimulated PBMCs could be regulated by IFN-y.

We report a hemolytic transfusion reaction with acute intravascular hemolysis due to anti-Jkb in a 49-year-old woman with uterine myoma. A patient experienced chills, fever, and red color urine following the transfusion of 1.25 units of packed red cells, shown to be compatible by the conventional cross-matching tube method. She had been received two units transfusion 3 weeks ago and there was no transfusion reaction at that time. One day after transfusion, her laboratory data showed total bilirubin 2.7 mg/dL, LDH 2,310 IU/L, and a trace positive direct antiglobulin test. Irregular antibody screening test was negative by the conventional tube methods but anti-Jkb was identified by column agglutination method. The presence of anti-Jkb provided an explanation for the acute hemolytic reaction. The hemolytic transfusion reaction was secondary responses following the previous transfusion. She showed severe hemoglobinuria, but renal failure did not develop and she was fully recovered with maintaining adequate renal output with IV diuretics.
